Attention procedures for the use and operation of pneumatic diaphragm pump

pneumatic diaphragm pump is powered by compressed air. The volume change caused by the reciprocating deformation of the diaphragm will greatly increase the export share of emerging countries. Its working principle is similar to that of plunger pump. The pneumatic diaphragm pump is used according to certain principles and methods, and according to certain instructions and precautions in the specific use and operation procedures, it can produce important use effects and contributions, and play a good use value. When using the pneumatic diaphragm pump to operate, the following points should be paid attention to: ensure that the maximum particles contained in the fluid when the fracture is very close to the particles at both ends of the test piece do not exceed the maximum safe passing particle diameter standard of the pump. Fasten the pump and all connecting pipe joints to prevent electrostatic sparks caused by vibration, impact and friction of the split pump. Use antistatic hose. To check and test the reliability of the grounding system periodically, the grounding resistance is required to be less than 100 ohms. Keep good exhaust and ventilation, and keep away from inflammables, explosives and heat sources. The inlet pressure should not exceed the maximum allowable pressure of the pump. Compressed air higher than the rated pressure of the pipeline pump may cause personal injury, property loss and damage to the performance of the pump

electrostatic sparks may cause explosion, resulting in personal injury and death accidents and property losses. Use wires with sufficient cross-sectional area as needed to properly and reliably ground the grounding screw on the pump. The grounding requirements shall meet the requirements of local laws and regulations and some special requirements on site. The exhaust of the pump may contain solids. Do not point the exhaust port towards the working area or people, so as to avoid personal injury. When the diaphragm fails, the material delivered by the sewage pump will be ejected from the exhaust muffler. Ensure that the pump pressure pipeline system can withstand the maximum output pressure, and ensure the cleanliness and normal working conditions of the multi-stage pump driven air circuit system. When transporting flammable and toxic fluids, please connect the outlet to a safe place away from the work area. Please use at least 3/8 "The pipe with smooth inner diameter and inner wall connects the exhaust port and muffler.

the high pressure of the fluid may cause serious personal injury and property damage. Please do not carry out any maintenance work on the pump" and the material pipe system when the pump is pressurized. If the rotor pump needs to be repaired, first cut off the air inlet of the pump, open the bypass pressure relief mechanism to relieve the pressure of the pipeline system, and slowly loosen the connected pipe joints. For example, the harmful and toxic fluid pump, eliminate Please do not send the pump directly to the manufacturer for repair. Properly handle according to local laws and regulations, and use genuine accessories of Shanghai wangquan Pump Co., Ltd. to ensure service life. The pump with aluminum alloy material used in the liquid delivery part should not be used to deliver the liquid containing fe3+ and halogenated hydrocarbons and other fixtures. If the fixture is a partial halogenated hydrocarbon solvent that often changes according to the change of material samples in the experimental machine, corrosion will occur and the pump body will burst. Ensure that all parts contacting the conveyor will not be corroded and damaged by the conveyed fluid. Ensure that all operators are familiar with the operation and use, master the precautions for safe use of the pump, and provide necessary protective articles if necessary. Use the pump correctly and do not allow long-term idling. (end)
